TCP Dynamic Proxy
The TCP dynamic proxy is similar to the TCP Proxy, but the listener is started from the Consul urlprefix tag. Also, the service is defined with IP and port, so that multiple services can be defined on the load balancer using the same TCP port. Connections are forwarded to services based on the combination of ip:port
To use TCP Dynamic proxy support the service needs to advertise
urlprefix-127.0.0.1:1234 proto=tcp in
Consul. In addition, fabio needs to be configured with a placeholder for the proxy.addr.:
fabio -proxy.addr '0.0.0.0:0;proto=tcp-dynamic;refresh=5s'
The TCP listener is started for the given TCP ports. To use IP addressing to separate the services, matching IP addressed would need to be added to the loopback interface on the host.
